Application filed March 3,

The present invention relates to improvements in window ventilators, and has reference to the type disclosed in Letters Patent No. 1,734,641, granted tome on November 5 1929. 1

7 The construction described in the said Letters Patent includes a deflecting frame, comprising an upper rail and a lower rail which are connected by side rails, and a screen frame which is hinged to the upper rail of said deflecting frame. While a construction of this type particularly adapts itself to wooden structures, difiiculties are presented when metal bars are used in constructing the deflecting frame and these difliculties cannot be overcome when it is desired to mount a single heavy glass pane in The main object of the present invention is to construct a deflecting frame which overcomes the difiiculties above referred to, and to generallysimplify the structure.

With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arrangement and construction of parts hereinafter described, pointed out in the appended claims and illustrated in the accompanying drawing, it being understood that many changes may be made of the several parts and details of construction within the scope of the appended claims, without departing from the spirit or sacrificing any of the ad vantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accompanying drawing, in which I Figure 1 is a perspective view showing the improved venti ator positioned on a window;

said ventilator, on a larger scale; and Fig. 3 is a section taken on line 3-3 of Fig. 2, on a still larger scale.

In the drawing, the lower sash of window casing 11. to be secured to the two substantially sheet metal plates or the numeral 10 indicates a window, slidable in a The ventilator, which is said casing, consists of triangular, preferably, brackets 12, attached by to the vertical members the said deflecting frame.

of the window casing immediately above the sill portion 14 thereof. These'brackets are so attached to the casing that they permitof ire-e sliding movement of. the windowsa shes,

their vertical edges15 being-forthis purpose spacedfrom the lower sash. The plates project into the'room, that isto say outward of the window frame, and their slanting edge portions 16 are each provided with two spaced flanges 17-, forming'a channel. Into these'channels, which are in aligmnent, may be slid adeflecting frame 18,'preferably made of metal. This frame tire :width of the window opening and. is adapted to receive-a glass panefl9. The deflectingframe is of U-shaped construction, it comprising a horizontalrail 20 fronreach end of which-rises a vertical rail extends across the en- 7 21. Between these rails is mounted, prefer-' ably, detachably,

is mounted a rubber or metalstrip 22, fora purpose hereinafter to be described. In or der to preventrattlingof the glass pane in the deflecting :frame, springs 23 may beinserted into the vertical'rails 21 of the frame, to bear against the saidfglasspane.

To the free ends of the vertical rails 21 is attached by hinges 25 a screen frame 26,

which extends in its operative position, horithe glass pane 19. On the upper free longitudinal edge of-the glass pane lower window sash, it: 7 upon inwardly ben-t cent the window sash carries a resilient strip 7 31 offelt, rubber or the like, the said strip being adapted to bear against the lower rail of the window sash or against the window pane when the sash is raised tope'rmit ventilation of the room. To the screen frame is fixed'a handle or knob 32, bymean's of which it may be raised'or lowered, as reqgulred. To the lower rail of the deflecting ion aperture and is directed upwardly, thus,

avoiding direct draft. The fabric screens the air, permitting thorough ventilation, without the accompanying annoyance of dust,zdirt and-Linsect's; vylf necessary, the screen framemay be shifted. around its hinges onto the. deflecting frame; More ZLlI IWlll thus-enter theroom but dust, dirt and insects will not :be" excluded therefrom.-

' The rubber or metal strip 22 above described serves-not only to make an air-tight joint with the screen frame but alsoto protect the windowi pane.- j. I

Both the deflecting frame and the screen frame maybe ,composedlof rails of any suitable cross-section, and they may be 'made of any suitable material, for instance extruded aluminum trails may be usedinflthe construction of these frames, and they may be hollow to decrease the weight thereof or to receive enlarged portions of the packing strips 31 and 33, as clearly;shownin Fig. 2 of the drawing. .Byconstructing the deflecting frame ofthree rails only, the'window pane may .be'detach'ed therefrom when it is to be v one of, its

cleaned. or replaced. I r

The rubber ormetal strip 22 may be held in place on, the deflecting frame by springs 34 (Fig. 3,), which may-beef any suitable construction and mounted on the vertical rails 21 of the deflecting frame. In the construction illustrated in Fig. 3-blade springs are employed, each spring being provided at ends with a loop 35, which is disposed within a rail 21; Through these loops pass screwbolts 36, which serve at the same time tosecure thehinges 25 to the said rails. The free ends 37 .of these springs bear against the strip.22. r

\Vhat I claim is p 1.,In combination with a window casing and a vertically sliding sash therein, of a pair of brackets secured to the vertical mem;v

, bers of said casing immediately above the sill portion thereof so as to PIOJGCt into theroom, a pair of channels formed in saidbrackets in alignment with one another, a deflecting; frame slidable in said channels and resting upon said sill, said frame comprisingtwo rails adapted to be disposed :in said channels and: connected by a rail adapted, to rest upon the-window sill, a window pane slidably arranged in said deflecting frame, horizontal flanges formed uponsaid brackets in alignment with the free ends of those de- 7 flecting frame rails which are disposed in said channels, a screen frame hingedly secured to those rails of said deflecting frame which are disposed in said bracket channels and adapted to rest upon the flanges of said brackets, the free longitudinal edge of said screen frame abutting against the lowerrail of said sash when the latter is raised to per mit access of air into the room through said screen frame.

2. The combinationaccording to claim 1, comprising a strip disposed upon the free edge of said pane, the rails of said deflecting frame being hollow, and a spring partly disposed vin each rail located in said; channels and secured to said rail, said springs bearing against said strip.
